PAM8106TVR

PAM8106TVR is a stereo class-D audio amplifier with spread-spectrum modulation, which offers high-quality, low THD+N, low EMI, and high PSRR. PAM8106 runs off a 4.5V to 15V supply with high efficiency up to 92% to eliminate the heat sink. With advanced EMI suppression by spread-spectrum modulation (SSM) technology, PAM8106 requires only inexpensive ferrite bead filters for audio outputs, while meeting EMC requirements for overall system cost reduction. PAM8106 integrates non-clipping power limit (NCPL) technology, which adjusts gain and eliminates the output signal clip due to the over-level input signal. PAM8106 also offers low THD+N and protects the speaker from damage. PAM8106 is fully protected against faults with short circuit protection and thermal shutdown, as well as undervoltage and DC input protection. Applications include flat monitor and LCD TVs, multi-media speaker system, DVD players, game machines, boom box and consumer electronics related application, music instruments.
